RHODES, a citibreakage and to distribute the draft between zen of the United States, residing at Barberthe carriage and the plow in a novel and imton, in the county of Summit and State of proved way.

My invention relates to a class of grading is a section on line 2 2 in Fig. 1.

IO and ditching machines in which a carriage or In the type of machine illustrated the plowwheeled body-frame is provided with a plow beam A is arranged alongside the carriage or for digging up the soil andan elevating carwheeled body-frame B and provided with a rier arranged for taking the loose soil from suitable plow C. It is also understood that the plow and delivering it at one side of the the plow-beam is suspended by a raising and I5 body-frame, the machine being drawnover lowering device substantially as in the patthe ground by a suitable number of horses. ents hereinbefore mentioned and that, as illus- AIn the class or type of these grading and trated in said patents, the machine is to be ditching machines to which my invention provided with an elevating-carrier for taking more particularly relates or is more desirably the plowed-up soil from the plow at one side 20 applicable a plow-beam provided with a suitof the machine and delivering such loose soil able plow is arranged at one side of the maatthe opposite side of the machine for wellchine and suspended by raising and lowering known purposes. devices, a good illustration of a machine of'V D indicatesthe forward swinging stay-bar, such general character being afforded by which is at one end hinged to the plow-beam `25 Letters Patent to Edwards and Durkee, No. in advance of the plow and at its opposite 275,614, April 10, 1883. end pivoted or hinged to the body-frame of Prior to my invention the plow has been the machine. The body-frame is provided at drawn from some portion of the carriageits forward end with a tongue or-pole E and as, for example, in patent to W. J. Edwards, with an evener F, arranged at the rear end of 30 No. 393,467, November 27, 1888, the plow is the pole, the evener in this illustration being drawn from the front axle or bolster by means provided with doubletrees G Cr, each having of a draft-chain attached at its rear end to va a `pair of swingletrees H, whereby the bodytransversely-arranged stay-bar for the plow-` frame can be drawn by the back team, combeam, in Letters Patent to W. H. Morenus, prising four horses abreast.

35 No. 690,451, the forward end of the draft- The evener Ifor the forward team of horses chain is attached to the rear end ofthe tongue is shown provided with two doubletrees K, or pole, while in a pending and allowed applihaving a pair of swingletrees L. The forward cation of Thomas J. Gray, Serial No. 158,258, evener I is not connected with the pole or with filed May 22, 1903, the draft-chain has its rear the body-frame, it being connected with `the 40 end attached to the plow-beam and its forward plow by a draft attachment so that during opend connected withthe evener,whichispivoted eration the wheeled body-frameor carriage upon the rear end of the pole and employed will be drawn by the back team,while the plow for the back team of horses. Owing to the will be drawn by the forward team, and hence great' draft strain upon the portions of the during heavy work the draft strain produced 45 carriage to which the plow has been thus conby back pullon the part of the plow will be nected, it frequently or occasionally happens on the forward team, while the draft strain that such portions of the carriage become incident to drawing the carriage along the broken. ground will be upon theback team.

The draft attachment illustrated comprises a chain M, having its rear end attached to the plow-beam at a point back of the stay-bar D, whereby it'is, in effect, connected with the plow. The chain M extends from its point of connection with the plow-beam forwardly and obliquely toward the middle of the front axle, where it is suitably guided, and then extended directly forward to connect with the rear end of a longitudinally-arranged rod N, which has its forward end connected with the evener I for the forward team, it being observed that this rod, broadly considered, is an extension of the chain M and that, if preferred, the rod N could be replaced by a chain arranged as a continuation of the chain M, although I regard the use of the rod N as a matter of further and special improvement. `he draft device thus arranged between the forward evener and the plow can be guided at the front axle or bolster by any suitable meansas, for example, the chain M can be provided with a long link or slotted plate O, engagingaguide pin, plate, or bolt upon the front bolster. In the specific arrangement shown this guide stud or pin is formed by the king-bolt P, which extends through the longitudinal slot in the link or plate O, the lower end of the king-bolt being provided with a head p, which is arranged under the plate or link O so as to support the latter. The slot in the plate or link O is of sufficient length to permit a desired extent of longitudinal play on the part of the draft attachment independently of the front axle, and by this arrangement the draft atguided at its forward end by a guide-loop P,

supported upon the pole, it being observed that the rod N, which forms a portion of the draft attachment, extends longitudinally and under the pole E. The rod N is also flexibly connected with the link or plate O-as, for example, bya link Q, connecting the rod with the clevis R, which is attached to the link or plate O by a vertical pivot fr.

I do not herein claim any of the matters described and claimed in the said application of rlhomas J. Gray, it being observed, however, that I herein illustrate a feature embodied in said application of Gray and consisting of a long link m, provided in the draft-chain M and arranged so that the stay-bar D can extend through it and at the same time have a desired extent of lateral play independently of the draft-chain or, conversely, permit the draftchain to have a desired extent of longitudinal movement independently of the stay-bar.

What I claim as my invention isl. In a ditching and grading machine, a wheeled body-frame provided with a plow, and an evener for a back team of horses; an evener for a forward team of horsesg-and a draft attachment arranged as a connection between the plow and the forward evener; the draft strain incident to the use of the plow being' upon the forward evener by means of the draft attachment and the resistance of the wheeled body-frame being upon the rear evener.

2. In a grading and ditching machine, a Wheeled body-frame provided with aplow and having an evener for a back team of horses; a forwardly-arranged evener for a forward team of horses; and a draft attachment connecting the forward evener with the plow and having a limited shifting connection with the middle forward portion of the body-frame.

3. In a grading and ditching machine, a wheeled body-frame having' a plow, and an evener for a back team of horses connected with the body-frame; a forwardly-arranged evener for a forward team of horses; Va draft attachment arranged as a connection between the forward evener and the plow and comprising in part a chain and in part a rod, the rod being arranged to extend forwardly from thc machine.

4. In a grading and ditchingr machine, a wheeled body-frame; a suspended plow-beam provided with a plow; a transversely-arranged stay-bar having hinged or pivotal connections with the plow-beam and the body-frame; and a draft attachment comprising a rod extending forwardly from the machine and a chain arranged as a connection'between said rod and the plow, said draft attachment being guided and maintained at a point midway of the front wheels.

5. In a ditching and grading machine, a wheeled body frame provided with a forwardly-extending pole and an evener for a back team of horses; a suspended plow-beam arranged at one side of the machine; a swinging' stay-bar having hinged or pivotal connections with the plow-beam of the body-frame; a forwardly-arranged evener fora forward team of horses disconnected from a pole; and a draft attachment connecting' the forward evener with the plow and arranged to extend from its rear end obliquely forward to the middle forward portion of the machine and thence directly forward under the pole to the forward evener, said draft attachment having' a shifting connection with the middle forward portion of the body-frame.
